IMPROVEMENT m PADnL'E-wnems.

The Schedule referred to these Letters Patent and making part of thesame and use the same, reference being had to the ac-- compan'yingdrawing forming part of this specifica tion.

This invention relates to improvements in feather- I ing paddle-wheelsfor steamboats, and consists in an improved arrangement of wheel orwheel-rim, mounted eccentrically to the paddle-wheel, and having thecranked axis of the buckets connected to it, for caus. ing thefeathering ofthe buckets, all as hereinafter more fully described.

Figure 1. is a side elevation of a paddlc-wheel and featheringapparatus,according to my invention, and in the working position.

Figure 2 is a side elevation of the same, when adjusted to throw thepaddles out of action, asit is sometimesrequired to do with one wheel,to turn in a short space.

Similar letters of reference indicate corresponding parts.

A are the paddle-wheels.

. the paddles.

1; the cranks connected to the axles, on which the said paddles arecapable of turning.

D is the wheel-rim to which the cranks are connected, and which ismounted eccentrically to the axis of the paddle-wheel.

This rim 1) has a smaller rim, E, by which it is mounted on thefriction-rollers F, so as to run eccentric-ally in the manner requiredfor the feathering action.

In this case the cranks are so set, relatively to the planes of thepaddles, that the horizontal plane of the axis of the eccentric wheel,when in the position for holding-the paddles in the working posit-ion,is considerably below the plane of the axis of the paddlewheel, and thevertical plane is a short distance to the left of the vertical plane ofthe paddle-wheel.

The grooved friction-wheels F, on which the wheelrim D is mounted, aremounted on the journals G of the crank-arms H, which are journaled at Iin suitable bearings, and these crank-arms are connected by bars K.

One of the axles at I is provided with a hand-lever, L, or it may be anyother suitable device by which it can be oscillated and held in therequired position for holding the said \vhcel rim, and for shifting itto throw the paddles out of action.

When this lever is in the vertical position, as shown in fig. l, thepaddle will be. in the working position,

and when turned down to the position shown in fig. 2, the paddles willbe shifted so as to run through the water edgewise, andhave little or nopropelling effee-t.

The combination, with the paddle-wheels and the paddles, of thewheel-rim D, rim E, grooved rollers 1 crank-arm H, bar K, and ashifting-lever, L, all arranged substantially as specified.
